LPC-LINK 2

LPC-Link 2 is an extensible, stand-alone debug adapter that can be configured to support various development tools

and IDEs by downloadable firmwares.

Available firmware images include:

LPCXpresso IDE debugger by NXP
CMSIS-DAP by ARM
J-Link by Segger (see more information here and specifically note the Terms of Use from Segger)

The board is supported by the LPCXpresso IDE and all development environments that supports the J-Link and CMSIS-DAP interface.

This product is delivered with a 10-pos IDC Ribbon Cable. Note that an adapter is needed to connect to the older 2x10-pos 100 mil pitch ARM debug connectors.

LPC-Link 2 is the latest addition to the LPCXpresso development platform.

There is an add-on board called LabTool that turn the LPC-Link 2 into a powerful debug tool with analogue oscilloscope and digital logic analyzer functionality.

Note

that LPC-Link 2 firmware in combination with the LPCXpresso IDE supports the Cortex-Mx cores in the LPC family,

but not the older ARM7/ARM9 cores. Read this FAQ entry for more information.

LPC-Link 2 firmware

SEGGER offers a firmware running on the NXP LPC-Link 2 platform

which makes the LPC-Link 2 compatible to J-Link Lite,

allowing users to take advantage of most J-Link features

like the ultra fast flash download and debugging speed or the free-to-use GDBServer,

by using a low-cost LPC-Link 2 platform for developing on evaluation boards.

Features

Supports all ARM based NXP devices which are also supported by J-Link Lite.
JTAG, SWD + SWO supported
Fully compatible to and same features as J-Link Lite

Limitations

The firmware making the LPC-Link 2 J-Link compatible has some limitations in contrast to an original, industry leading SEGGER J-Link:

May be used with ARM based NXP devices only.
Only debugging on evaluation boards is allowed.
Debugging on custom hardware is not supported and not allowed.
No production flash programming support.
Unlimited breakpoints in flash available for evaluation only.
No support is given.

By using an original SEGGER J-Link PRO, J-Link ULTRA+ or J-Link PLUS, all these limitations will be gone.

Using LPC-Link2 as an evaluation board

LPC-Link2 can also be used as an evaluation board for the NXP LPC4370 MCU, a 204 MHz Cortex-M4 MCU with an 80 MHz ADC and two extra Cortex-M0 cores.

LPC-Link2 is designed to be booted from USB, making it very simple to re-purpose the board by simply power cycling it and downloading a new program into the board via USB, using the DFUSec tool ! If you don't want to use the USB boot capability to boot the board on each power cycle, a 1MB SPIFI FLASH is also available on the board for standalone operation.

Or if you have access to another debug probe - such as another LPC-Link2 - you can use the SWD/JTAG connector on the board to download and debug applications with an IDE such as Keil, IAR, or LPCXpresso.

There is more information on this in the FAQ "Using an LPC-Link2 as an LPC4370 evaluation board".

Getting started with LPC-Link 2

In order to get started with LPC-Link 2 just a few steps are necessary:

Download the LPC-Link 2 configuration tool here
Start the LPC Link configuration tool WITHOUT having LPC-Link 2 connected to the PC.
In the configuration tool, select J-Link firmware as image to be downloaded
Follow the instructions in the configuration tool
Power-cycle LPC-Link 2. It will now enumerate as a J-Link

LPC-Link 2 Configuration Tool

Important Notes : Read before downloading and using

The use of the LPC-Link2 Configuration Tool is no longer recommended
The functionality offered by this tool has been superseded by LPCScrypt.
Download LPCScrypt to obtain the latest versions of CMSIS-DAP
and J-Link firmware for LPC-Link2 or LPCXpresso V2/V3 boards.

The LPC-Link 2 Configuration Tool (LCT) is a Windows tool that installs the CMSIS-DAP/VCOM/LPCSIO
or JLINK firmware on LPCXpresso V2/V3 and LPC-Link 2 boards.

This package provides the Link Configuration Tool, all necessary Windows drivers, a User Manual,
and the source and project files to rebuild the programming algorithm firmware used by the LCT.

The V2 version provides expanded capability for LPCXpresso V2/V3 boards with improvements to CMSIS-DAP,
a UART bridge connected to the target processor (LPCXpresso V2/V3 boards only),
and a LPCSIO bridge that provides communication to I2C and SPI slave devices on LPCXpresso V3 boards.

For LPC-Link 2 boards, an updated version of CMSIS-DAP provides faster programming and more stable operation.

This version also adds support for J-Link - please see SEGGER's website for more information:

for lpc-link2 boards and for LPCXpresso V2/V3 boards.

Firmware included in this package:

LPCXpresso V2/V3 boards: CMSIS-DAP debugger + VCOM (UART bridge connected to target processor)
+ LPCSIO bridge (I2C + SPI + GPIO bridge connected to target processor)
LPC-Link 2 boards: CMSIS-DAP firmware
LPC-Link 2 and LPCXpresso V2 and V3 boards: J-Link firmware

If you are using LPC-Link 2 or LPCXpresso V2/V3 boards with the LPCXpresso-IDE, you do not need to use this tool.

Note that the LCT requires NET4.5.1 to be installed prior to use.

This package will automatically download and install NET4.5.1 if it is needed.

The older v1.xx versions of the LCT require NET4 to be download and installed manually prior to use.

Getting Started

Go here to get a quick guide on how to use the LCT tool to install firmware on supported boards. The LCT installer will install a User Manual that shows the LCT steps to program the firmware into your board. This User Manual can be selected from the start menu.

Known issues

The LCT may not correctly enumerate when used with a Virtual Machine (VM). It is recommended not to use this on a VM.
Version of the LCT >= v2.01 will not work on Windows XP systems. You can only use the v2.00 older version for Windows XP systems. Download it here.

LPCScrypt Overview

Important Note :

From v1.5 onwards, LPCScrypt is the recommenced tool for programming the latest versions

of CMSIS-DAP and J-Link firmware onto LPC-Link2 or LPCXpresso V2/V3 boards.

LPCScrypt is a command-line based, fast flash, EEPROM, OTP

and security programming tool for the LPC1800 and LPC4300 series of microcontrollers.

Key features include:

Multi-Platform Support (Windows, Mac, Linux)
Scriptable command line interface
Programming of internal and SPIFI flash
- Support for a wide range of SPIFI devices (via use of LPCOpen lpcspifilib)
- Optimised for high speed operation - typically 100-300KB/sec,
  depending upon flash device, host OS and host computer.
Programming EEPROM (internal flash parts only)
Programming One-Time Programmable (OTP) memory
Images and scripts to program LPC-Link2 and LPCXpresso V2/V3 debug probe firmware

LPCScrypt consists of two parts, a multi-platform command line tool and an MCU firmware monitor.

In use, the firmware monitor is downloaded to the target MCU

using USB DFU support built into the on-chip ROM (using USB0 or USB1).

The firmware creates a virtual serial port (VCOM) over USB to communicate with the host.

The LPCScrypt host tool provides a command-line interface to the firmware,

giving access to the programmable features of the MCU.

It can be invoked with a single command or a script file containing a sequence of commands.

Standard host tools, such as Windows batch files or Linux/Mac shell scripts,

can be used with the LPCScrypt host tool to automate multiple operations,

such as binary file encryption, programming binary files to flash devices,

setting boot options, configuring VID/PID, and finally simulating MCU reset.

LPCScrypt is flexible and fast, and is suitable for one off programming and testing or semi-automated production programming.

An enhanced version of LPCScrypt with additional support for the security features of the LPC18S00 and LPC43S00 parts is available,

subject to Export Control regulations. This enhanced version adds:

Generating and programming 128 bit AES keys
Encrypting and programming secure images

Contact your local NXP representative to obtain the enhanced version.
